those they promised her not to do. They
were just different, that was all.

Sue and Bunny went down to the edge of Lake Wanda. They could not see
their father's boat, so they walked along the shore. Before they knew it
they had gone farther than they had ever gone before, and, all at once,
in the side of the hill, that led down to the beach of the lake, they
saw a hole that seemed to go away back under the hill.

"Oh, what's that?" asked Sue, stepping a little behind Bunny.

"It's a cave," answered her brother.

"What's a cave?" Sue next asked.

"Well, a cave is a hole," explained Bunny.

"Then a hole and a cave are the same thing," said Sue.

"Yes, I guess they are pretty much," admitted the little boy. "Only in a
cave you have adventures, and in a hole you only fall down and get your
clothes dirty."

"Don't you ever get your clothes dirty in a cave?" Sue demanded.

"Oh, yes, but that's different. Nobody minds how dirty your clothes get
if you have an adventure in a cave," Bunny said.

"And can we go into this one?" Sue asked.

"I guess so," answered Bunny. "Mother told us not to get in any boats,
and we're not. A cave isn't a boat. Come on."

"See, Splash is going in," pointed out Sue. "If he isn't afraid we
oughtn't to be."

"Who's afraid?" asked Bunny. "I'm not!" And with that he walked into the
cave. As he still held Sue's hand he dragged her along with him, and as
Sue did not want to be left alone on the beach of the lake, she
followed. Bunny saw Splash running ahead. For a little way into the cave
it was light, but it soon began to darken, as the sun could not shine
in that far.

"Oh, I don't want to go any farther," said Sue. "It's dark. If I had my
Teddy bear I could make a light with her eyes."

"I've got something better than that," said Bunny.

"What?" asked Sue.

"My pocket flashlight I got for Christmas. That gives a good light. Come
on, now we can see."

From his pocket Bunny took the little flashlight. It was the same kind,
made with the same storage dry battery, that ran his train and lighted
the Teddy bear's eyes.

"Yes, now I can see!" cried Sue. "I'm not afraid any more."

With Bunny holding the light, the two children went farther on into the
cave. They were looking about, wondering what they would find, when, all
of a sudden, there was a noise farther in.

"Oh!" cried Sue. "Did you hear that?"

"Yes," answered Bunny, "I did. What was it?"

Splash began to bark.

"Qu
